APP FREEZES IF PERMISSIONS ARE REJECTED BEFORE LAUNCHING

The tracker app freezes at the splashcreen if the permissions are denied on launching/installing the app.
POSSIBLE FIX
If permissions are denied it should show a rational or dialog that explains why the permissions are needed and prompts the users to accept them or the settings when it is permanently denied.

Start by reproducing the freeze when permissions are denied before launch or during installation, then inspect the app's permission-handling entry point. The work is done when denial no longer leaves the app at the splash screen and the user receives an explanation with a way to accept permissions or open settings after permanent denial.
